Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645748, here are decompositions:

19 + 8645729 = 8645748
29 + 8645719 = 8645748
61 + 8645687 = 8645748
79 + 8645669 = 8645748
101 + 8645647 = 8645748
131 + 8645617 = 8645748
151 + 8645597 = 8645748
257 + 8645491 = 8645748

Showing the first eight; more decompositions exist.
